Wow, that was excellent. I really had to laugh out loud just from enjoying the singing and watching the girls roll their heads while air-guitaring! And that guy on the right with the leather pants and jacket sure made a good Bruce ;-)
I wish more kids these days would receive education like this, especially to learn what other music exists beside what's in the charts. Reminds me that I got hooked on Maiden in kinda the same way, by listening to Brave New World (the song, then the record, then the Rock in Rio concert DVD) because we read that book in my English class when I was 19. We had the song incorporated in our analysis of the book, an idea by a fellow student.
